Welcome to Lecture 02 of Chapter 02 – Mole Concept, one of the most scoring and concept-building topics in Chemistry for NDA, CDS, Airforce X/Y, and all defence examinations.
In this lecture, we continue the foundational concepts of the Mole, covering molar mass, atomic mass, molecular mass, formula mass, and methods to calculate moles using different formulas.

This lecture is extremely important from the NDA exam point of view, as questions on mole calculation, mass-to-mole conversion, number of particles, and Avogadro’s constant appear frequently in the written exam. The concepts explained here form the base for stoichiometry, chemical equations, and numerical problem-solving in higher chapters.
